9. Which one of the following statements is correct in the context of erythromycin-mediated inhibition of protein synthesis in bacteria?

(1) Erythromycin inhibits protein synthesis at the step of elongation, but it nonetheless allows translation of the first few codons.
(2) Erythromycin inhibits protein synthesis at the step of elongation, and it prevents formation of even the first peptide bond.
(3) Erythromycin inhibits formation of the translation initiation complex.
(4) Erythromycin is toxic to bacteria because it results in initiation of protein synthesis with elongatortRNAs.
